Hi list,
My attention was drawn to the foreach package by recent posts...I
decided to have a look...
I'm using R.2.9.1 on Windows, I have downloaded the foreach package
today (v 1.2.1), together with iterators (v. 1.0.1) and codetools (v.0.2-2).
Full of hope I try the most simple thing of all out of the package
vignette :
x <- foreach(i = 1:3) %do% sqrt(i)
and get :
Erreur dans sqrt(i) : indice hors limites ( i.e. "error in sqrt(i) :
index out of bounds")
but when trying :
x<-foreach(i = 1:3) %do% print(sqrt(i))
I get :
[1] 1
[1] 1.414214
[1] 1.732051
Erreur dans print(sqrt(i)) : indice hors limites
Probably I didn't drink enough coffee this morning and I'm still asleep
: it is obvious that I miss a point... but I am unable to see which one.
Any help appreciated ! Many thanks, and very best regards Olivier
